136. Although schistosomiasis is not often fatal, it is so debilitating that it has become an economic drain on many developing countries. A. it is so debilitating that it has become an economic B. it is of such debilitation, it has become an economical C. so debilitating is it as to become an economic D. such is its debilitation, it becomes an economical E. there is so much debilitation that it has become an economical 请问:选项C错误的原因是什么?是So引导的倒装只能出现在整个句子的开头,还是as to become 没有表达出that it has become 的完成时的意思? 我觉得as to become 已经表达出完成的意思,并且也比that从句精练呀。
在GMAT中所有见到了题目关于SO THAT和SO AS TO中,绝大部分采用的是SO THAT,基本解释都是SO THAT简洁,偶尔出现过SO... AS TO的选择,也是因为SO THAT其他的错误,所以我觉得,在没有其他错误的时候SO THAT要比SO ... as to简洁。同时,SO AS TO比so ... as to出现得少得多,几乎可以认为在GMAT中后者更好。 以上为参考,我觉得绝大多数情况下GMAT所采取的形式都是比较书面的和规范的方式。
